Diary of the Dead: I loved this one mainly because of the ending
How one of the characters questions weather we are even worth saving all whilst it's showing a clip of a couple guys using a female zombie who is hanging from a tree as target practice.
I don't know why but that ending stuck with me it was simple but effective.
28 Weeks Later: I question weather this and 28 Days Later can actually be classified as zombie films because technically they aren't actually zombies it's just a virus that makes people uncontrollably angry but ill throw it on my list any way because i loved this movie and i sort of see it as a "realistic" view on if there was going to be a zombie like apocalypse this would be it.
but i use realistic very loosely because even this scenario is a bit out there but it's far more closer to being realistic than the dead coming back to life.
Rec:I normally hate movies set in a single place but i absolutely loved this movie.This is a FANTASTICALLY creepy and atmospheric zombie movie instead of doing the whole zombies taken over the world scenario this is set just in a apartment building but the way it's filmed and the fact there is no music or over the top sound effects really play a big role in making this zombie movie probably one of the creepiest horror movies Ive seen and the ending is just down right bone chilling i highly recommend this film for zombie fans and just horror fans in general.
By the way there was a American remake titled Quarantine but i recommend seeing the original Rec but just warning you Rec is subtitled but believe me it's so much better than the remake.
Dawn of the Dead remake: This very rarely happens but i loved the remake more than the original it's just a fantastic action/zombie film extremely entertaining.
Shaun of the Dead: This right here is horror comedy in general done right hilarious and entertaining and one of the only comedy's at the time that was actually funny.
Zombieland: This is a dead set classic and i loved the step by step survival guide very funny.
Honorable mention this isn't a movie but a short TV series called Dead Set i recommend zombie lovers check it out it's quite good.
